Can hay fertilized with chicken manure cause salmonella in horses?

Yes, hay fertilized with chicken manure can cause salmonella in horses. Salmonella is a type of bacteria that can cause illness in both humans and animals. It is typically found in the intestines of animals, and can be spread through contact with contaminated food, water, or surfaces.

When chicken manure is used as fertilizer, it can come into contact with hay and other plants that are consumed by horses. If the manure is not properly composted, it can contain harmful bacteria, including salmonella. Horses that ingest hay or other feed that has been contaminated with salmonella can become infected with the bacteria and develop illness.

Symptoms of salmonella infection in horses can include diarrhea, fever, lethargy, and loss of appetite. In severe cases, salmonella infection can lead to death. If you are concerned that your horse may have been exposed to salmonella, it is important to contact your veterinarian immediately.
